Объект исследования - земляника садовая сорта Фреска. Целью исследования послужило изучение влияния регуляторов роста и активированного угля на микроклональное размножение вышеуказанного сорта земляники садовой. Семена стерилизовали 0,1% раствором нитрата серебра, затем промывали раствором хлорида натрия, далее производили трехкратную промывку стерильной дистиллированной водой. Для проращивания семян использовали питательную среду по прописи Мурасиге-Скуга без регуляторов роста (МС0 ). Для исследования влияния регуляторов роста на развитие растений использовали питательные среды МС с добавлением 6-бензиламинопурина (МС+0,5 мг/л 6-БАП; МС+1,0 мг/л 6-БАП) и тидиазурона (МС+0,5 мг/л ТДЗ). В качестве контроля использовали МС0 . Культуральные сосуды помещали под холодный белый флуоресцентный свет, фотопериод 16/8 ч свет/темнота, температур 23±2°C. Для проращивания семян достаточно использовать питательную среду Мурасиге и Скуга без регуляторов роста. Эффективность стерилизации семян 0,1% раствором нитрата серебра была достаточно высокой и составила 97,5%. Однако, качество коммерческих семян было низким, и мы получили лишь 3,9% жизнеспособных сеянцев. Далее было изучено влияние вышеуказанных концентраций регуляторов роста на регенерационный потенциал сеянцев, с использованием в качестве базальной среды компонентного состава по прописи Мурасиге и Скуга. Показано, что применение тидиазурона приводит к некрозу тканей и полной гибели микрорастений, как при культивировании проростков, так и при пересадке на данную среду целых растений. А 6- бензиламинопурин положительно влияет на эффективность микроразмножения земляники садовой сорта Фреска. В нашем случае 6-бензиламинопурин приводил к увеличению коэффициента размножения и индукции ризогенеза (МС+0,5 мг/л 6-БАП). Следует отметить, что добавление в питательную среду активированного угля стимулировало рост микрорастений, но при этом снижался коэффициент размножения (1,0 мг/л 6-БАП). Образование корневой системы регистрировали у всех клонов, которые помещали на среду Мурасиге и Скуга базальную и с содержанием 6-бензиламинопурина.</p></abstract><trans-abstract xml:lang="en"><p>For the first time, a protocol of microclonal propagation for garden strawberries of ‘Fresca’ cv. from seeds has been developed, including introduction to culture, reproduction and rooting. The object of the study is a strawberry of the garden cultivar ‘Fresca’. The objective of the study was to study the effect of growth regulators and activated carbon on microclonal propagation of the above-mentioned garden strawberry cultivar. The seeds were sterilized with a 0.1% solution of silver nitrate, then washed with a solution of sodium chloride, then washed three times with sterile distilled water. For seed germination, a nutrient medium was used according to the Murashige and Skoog recipe without growth regulators (MS0 ). To study the effect of growth regulators on plant development, MS nutrient media with the addition of 6-benzylaminopurine (MS+0.5 mg/l 6-BAP; MS+1.0 mg/l 6-BAP) and thidiazuron (MS+0.5 mg/l TDZ) were used. MS0 was used as a control. Culture vessels were placed under cool white fluorescent light, photoperiod 16/8 h light/dark, temperature 23 ± 2 °C. To germinate seeds, it is enough to use the Murashige and Skoog nutrient medium without growth regulators. The effectiveness of seed sterilization with 0.1% silver nitrate solution was quite high and amounted to 97.5%. However, the quality of commercial seeds was low and we received only 3.9% of viable seedlings. Further, the influence of the above concentrations of growth regulators on the regeneration potential of seedlings was studied, using a component composition according to Murashige and Skoog as a basal medium. The limiting factors in the microclonal reproduction of this strawberry cultivar are growth regulators and their concentrations. It is shown that the use of thidiazuron leads to tissue necrosis and complete death of microplants, both during the cultivation of seedlings and when transplanting whole plants to this medium. And 6-benzylaminopurine has a positive effect on the effectiveness of micro-propagation of strawberries of the garden cultivar ‘Fresca’. In our case, 6- benzylaminopurine led to an increase in the multiplication factor and the induction of rhizogenesis (MS+0.5 mg/l 6-BAP). It should be noted that the addition of activated carbon to the nutrient medium stimulated the growth of microplants, but at the same time the multiplication factor decreased (MS+1 mg/l 6-BAP). The formation of the root system was recorded in all clones that were placed on a Murashige and Skoog basal medium and containing 6-benzylaminopurine.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>земляника садовая</kwd><kwd>микроклональное размножение</kwd><kwd>садоводство</kwd><kwd>регулятор роста растений</kwd><kwd>6-бензиламинопурин</kwd><kwd>тидиазурон</kwd></kwd-group><kwd-group xml:lang="en"><kwd>strawberry</kwd><kwd>micropropagation</kwd><kwd>horticulture</kwd><kwd>plant growth regulator</kwd><kwd>6-benzylaminopurine</kwd><kwd>thidiazuron</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа была выполнена на уникальной научной установке «Коллекция живых растений in vitro Ботанического сада-института ДВО РАН» (реестровый номер регистрации на сайте http://ckp-rf.ru – 347296) в рамках темы государственного задания «Введение в культуру, изучение и сохранение генетических ресурсов хозяйственно ценных растений Восточной Азии».
